The shafts 18are provided outside of the bear-- ings 17 with sprocket-wheels 85 overwhich runs 'a sprocket-chain 86 communicating motion from one roller 19to the other.

The `rollers 19 are caused to rotate and thereby revolve a tire mountedthereon by .the following mechanism: Mounted on one of the shafts 18,preferably the left onein Fig. 2 and the front one in Fig. 1, is a bevelgear 21 arranged to mesh with a bevel- ,pinion 22 Splined on a verticalVshaft 23 mounted in suitable bearings in the base 3 and head 4 of4thestandard 2. The carriage 15 isprovided with a laterally-projectingapertured lug24 which receives the shaft 23 Vand which serves to supportthe beveled pinion 22 and 'to cause its vertical which forms the drivingmember o a clutch,'

a driven 'member 32 is splined on the shaft 28 and is adapted to engagetherewith when shifted through the medium of a lever 33 fulcrumed at 34on the bracket 30 and operated by a pull rod 35 the handle of which ispositioned within ready access of the operator when standing at the leftof the machine i'n Fig. 2.

It will be noted that lwhen the vertical position of the carriage 15 hasbeen `secured, the member 32 of the clutch is shift- Y edinto clutchingrelation with the pulley 31 and a motion is communicated to the latterthrpu h the medium of any instrumentality such or instance as a belt,the rollers 19 will be rotated in vunison lin the same direction and.consequently revolve a core 2() mounted thereon. Mounted on the upperfaces of the heads 4 of the standards 1 and 2 is anA inverted U-shapedframe provided with two downwardly-extending legs 36 and 37 resting onthe heads f4 and secured thereto by any suitable mechanism. In order tosustain the upper portion of a tire or other annular object mountedonthe rollers 19 during the revolution thereof, guidin mechanism which isshown in detail in Flg. 7, is provided. This mechanism consists of ahorizontal threaded shaft 38'bearin a hand wheel 39 by whichit islrevolved an is supported in a threaded bearing 40 so that as the shaft38 is rotated it is shifted horizontally, Secured tothe inner end of theshaft 38 is a. volw/41 bearing a guiding roller 42 sizes.

'90 W ndz'ng mechanism-Briefly, 'thewinding mechanism embodies a pair of broken-A annuli revolving on offsetaxes of revolution and constituting a shuttle or a bobbin-car rier. Indetail, there is provided on the 95 front face of the U-shaped frame inFi l,

a plurality of flanged rollers 51 arrange at the angles of an imaginaryhexagon so that an annulus may be revolved on their periph-n eries. Alsosecured on the front face of the det U-shaped frame is a condseriesofroll: ers 52 arranged eccentrically vvithrespect to the 'series .ofrollers 51. Mounted on the peripheries of the rollers 51 is a broken an,.gz-. nulus 53pm-vided nea'r the boker'rportion'- *los withcounterweights 54'and also rovidedl with a series' of apertures in wichra'e mounted wrist-pins 55.-` The frontfac'e the annulus 53 1s alsoprovided with a pht I rality of horizontally-projecting pins 84 for 11oa: purpose to belater `lescribved. Y

The axisv of the annulus 53-is 'at 57. Rev' olubly mounted on theperipheries of the rollers 52 is a second annulus 58 theaxis' of whichis at 59. This annulus is also provided "11i`$ with a plurality ofapertures inwhich are mounted wrist-pins 60 a.nd connecting"t he.wrist-pins 55 in the ann'ulus 53 With. the ad# jacent wrist-'pins 60 inthe annulus 58 .are,

links G1 vfor a purpose to be later describedig'12`0' The two annu'liare adapted to constitute a' shuttle'and are arranged to revolve inunison inthe same direction during' both the wiid'- ing and theunyvinding operations and the revolutionpof these annuli-is effected bythe 125 following mechan'em: Y In fafsuitable bearin extending throughthe U-shaped frame 36 1s a shaft 62 bearing near its rear end a sprocketwheel 63 which receives a sprocket chain 64 running overa 130 sprocketwheel 65 tlxedly secured on the Ymunicated from the driving shaft Q8 tothe vshaft 62 the annulus`53 will be revolved.

A b1 't-stretcher- 7 0 is employed for 1naintaining tensiony on ,thebelt 69 but as this beltstretcher may be of any ordinary construction adetailed description thereof is believed to be unnecessary. Thecountcrweights 54 are positioned on the annulus 52 to counterbalance thebobbin and its carrier, a detailed description of which follows:

Bobbi'n. und carriera-The mechanism, by

- which .a strip of material is wound onto and unwound from a tire orother object, em-

.bodies a bobbncarrier and a bobbin so ar` rangedfthat the bobbin ispermitted to rotate on its own axis, protected hy a .tension device,during the placement of a strip. of material and arranged to be heldagainst independent rotation on its own axis during the unwinding ofastrip of material from an object.'

In detail, annulus 53 opposite to the. broken portion is prpvided with atransverse` opening constitntlngy a bearing in which is mounted a shaftl71 4'formed integral with a crank -72'positioned rearwardly ofthe andnulus 53 and between it and the annulus 58.

The latter' annulus is also provided with an opening to receive awrist-pin 73 on the opposite end of the crank 72 so that as the annulirevolve in unison the position of the l crankar'm 72 will always bevertical vand this is also true of the links 6l which connect thewrist-pins 55 and 60. B this arrange -Utation .thereon would alwaysnormally maintainits relative position during its orbital movement aboutthe tire 20. The shaft 71 in front of the annulus 53 is provided With aAhub 74 from which projects a boss 75 provided with a lateraliextending.,y arm 76. The portion 82 of t e shaft 71 which projectsforwardly from the boss 74 bears a rotatable drum 77 around which is aband-brake 78 one end of Which is anchored at 79, (see'Figs. l and 6) tothe arm 76 and the opposite end of the band is secured to a threadedshaft 80 extending through a suitable aperture in the arm 76 to receivea thumb nut 80 by which the bandbrake 7-8 is contracted for tensionin oren tircly preventing the revolution of t e bobbin-carrier 77. 0n thefront face of the bobbin-carricr are a pair of pins 8l adapted to bereceived in suitably-formed apertures in the rear face of the,bobbin 82for detachably connecting' the` bobbin 8" to the bobbin-carrier andinducing or preventing rotation of one `with respect tothe other. Thebobbin is held on the port-ion 82 of the shaft 71 through the `medium ofa nut 83 held in position by a bayonet joint, `or any other preferableor approved means so that the bobbin may be readily placed on theshaft-,wand removed therefrom.

` The placement of a. stri i ot material on an object sucl as atire isillustrated in detail in Fig. 3, and in this instance the stri ofmaterial rs'seeured to the riglvside o the tire in this ti ure and theshuttle embodying Mthegtwo annu i is revolved in the direction of thearrow and a suitable degree of tension is imposed on the bobbin carrierthrough the medium of thebandbrake 78 to place the required amount oftension on the strip during its lacement. During the orbital movement othe bobbin 82 about the tire 9.0 the latter, of course, is revolved onits own axis throu h the mechanism 'already described and t e revolutionof the bobbin about the tire is maintained until a sutii'cient has beenlaced on the tire.

Supply y `relative position, of the crank will be maintained atalltimes.

1fl it is desired to `unwind a previously placed strip from the tire theband-brake is .tightened sullicientlyto prevent. independen t rotationofthe bobbur and its carrier and the shuttle is revolved in the samedirection as it is during the placement ot a strip, but ther strip istaken from theoppo- 'site side of the tire,'or to be more exact, theAtire is reversed in position and as the bobbin orbitally revolves aboutthe tire in the direction of the arrow, the strip of material is Wound uon the bobbin, see Fig. 4. WVhen it is esired toimpose an additionaltension upon the strip durmg its placements, then strip is carriedaround one or more of the pins 84 on the annulus 53,

From the foregoing it will be seen that the shuttle is rotated in thesame direction both for the placement of a strip. of material and itsremoval from an object and that it is not necessary to reverse therevolution of the shuttle for the two oherations, the only requirementbeing that tlie position of the tire or other object be reversed duringthe unwinding of a strip of material therefrom.
